Capilla de Loreto, Catholic chapel in Plaza de Armas, Cusco, Peru.

Capilla de Loreto is a chapel beside the Iglesia de la Compañía on the Plaza de Armas in Cusco, at the corner with Intik'ijllu street. It has its own door to the square and another opening into the main church. Built from 1651 to 1653 under friar Juan Bautista Egidiano, its facade bears an inscription giving 1654 as the completion date.

The first Jesuit church on this site was projected in 1571 with two side chapels. After the 1650 earthquake forced its demolition, both chapels were rebuilt from 1651 to 1653 under friar Juan Bautista Egidiano, though a facade inscription gives 1654. This chapel, at the corner of the plaza and Intik'ijllu street, served the indigenous congregation and was consecrated to Our Lady of Loreto until 1894, when bishops Pedro José Tordoya and Juan Antonio Falcón changed the dedication to Our Lady of Lourdes.

The chapel blends Catholic devotion with local traditions through its mixed architectural style that reflects both Spanish and indigenous influences. Visitors today can observe how two cultures merged in a single structure through the careful stonework and design choices.

The chapel remains open throughout the year and sits beside Loreto Street, which has numerous artisan shops selling regional crafts. Visitors can easily explore the area on foot since it sits directly on the main plaza.

The Inca stonework in the chapel walls displays a sophisticated technique where blocks decrease in size from bottom to top and fit together without mortar. This pre-Hispanic engineering skill remains visible today and shows the precision the builders achieved without modern tools.
